Isobatic

The temperature of a gas is raised, all of the energy transfers to heat, and no work is done

The temperature of a gas is raised, all of the energy transfers to work, and no heat is released

A gas takes in heat, does work, and the internal temperature of the gas does not change

Work is done on a gas, its temperature rises, and no energy is released in the form of heat

A gas maintains a constant level of heat, temperature, and work
